ObjectiveTo evaluate the combination of 7 interventional pulmonology methods in early diagnosis of lung cancer.MethodsA total of 467 patients with thoracic and pulmonary lesions (include hilum pulmonis lymphadenectasis, mediastinal lymphadenectasis, pulmonary scobination, lump, lamellar infiltration, small amount of pleural fluid and pleural scobination) had negative results via exfoliative cytology, bacteriology and routine bronchoscopy. All these patients had ultrathin bronchoscopy with biopsy and brushing. For those 155 cases whose foci were located at porta pulmonis, inner zone or median zone, the authors applied ultrathin bronchoscopy with biopsy and brushing guided by X-ray. For those 95 cases whose foci were located at median zone or outer zone and unconnected with chest wall, per cutem lung puncture needle aspiration was employed under the guidance of X-ray. For those 102 cases whose foci were tightly connected with pleural membrane, per cutem lung puncture biopsy was employed under the guidance of type-B ultrasonic. For those 59 cases with suspected central airway foci, auto-fluorescence bronchoscopic biopsy and brushing were employed. For those 67 cases with hilum pulmonis or mediastinal lymphadenectasis, endobronchial ultrasonic transbronchial needle aspiration (EBUS-TBNA) was employed. For those 23 cases with small amount of pleural fluid or pleural scobination, electronic thoracoscopic biopsy and brushing were employed.ResultsIt was found that 118 cases were diagnosed by ultrathin bronchoscopic biopsy and brushing with a positive rate of 25.3% (118/467), 105 cases by ultrathin bronchoscopy with biopsy and brushing guided by X-ray with a positive rate of 67.7% (105/155), 63 cases by per cutem lung puncture needle aspiration under the guidance of X-ray with a positive rate of 66.3% (63/95), 69 cases by per cutem lung puncture biopsy under the guidance of type-B ultrasound with a positive rate of 67.6% (69/102), 18 cases by auto-fluorescence bronchoscopic biopsy and brushing with a positive rate of 35.3% (18/51), 52 cases by EBUS-TBNA with a positive rate of 77.6% (52/67), 12 cases by electronic thoracoscopic biopsy and brushing with a positive rate of 52.2% (12/23). The total positive diagnostic rate was 93.6% (437/467). And the diagnostic rate of < or = stage II lung cancer (3 cases carcinoma in situ, 84 stage I a, 63 stage Ib, 65 stage IIa and 44 stage IIb) was 82.7% (259/313).ConclusionJoint application of these 7 interventional bronchoscopic techniques can significantly boost the rate of early diagnosis of lung cancer.
